You don't make a dime until you sell.....and you don't LOSE a dime until you sell either. When to cut your losses and get out has been a lot harder decision in my experiance. I was up 250% on Food Lion Supermarkets back in the 80s when they got hit with a tainted meat scandal. The stock dropped like a stone on insane volume and I could/would not let go. When I finally sold a year later the opportunity costs of holding had made the losses even worse!!
